As a result of comminuting iron ore and granite and iron‐ore have grindability values of 0.061 g/rev and rock, it is important to determine the hardness and the 0.926 g/rev respectively. This confirmed that granite requires grindability characteristics of both materials so that more energy to be grinded.

XRD analysis showed the crystalline content of the sample. It was found that the microwave treated iron ore has peak more than that of untreated ore, i.e. the crystallinity increased with the microwave exposure time. The calculation of HGGI indicated increase in the ease of grinding or decrease in grindability index of the microwave treated ore.

The calculation of Hard Grove Grindability Index indicated increase in the ease of grinding of microwave treated iron ore than the untreated which is also confirmed by specific rate of breakage (S i) values. Consequently, it was concluded that the microwave assisted grinding was produced good results particularly for grinding characteristics.
